[0039] See Figures 1 to 12 The present application provides a drive module 10 for a reagent handling device.

[0040] The driving module 10 comprises a support frame 100, a rotating frame 200, a lubrication stabilizer 300, a movable rod 400, a first driving assembly 500 and a second driving assembly 600. The rotating frame 200 is rotatably installed on the support frame 100. The lubrication stabilizer 300 is installed on the support frame 100 or the rotating frame 200 and is formed with a through hole 310, and the lubrication stabilizer 300 is formed with a protrusion 320 in the through hole 310. The movable rod 400 penetrates through the through hole 310 and abuts against the protrusion 320, and one end of the movable rod 400 is movably installed on the rotating frame 200 in the vertical direction. The first driving assembly 500 is installed on the support frame 100 and is in driving connection with the rotating frame 200. The first driving assembly 500 is used to drive the rotating frame 200 to rotate in the horizontal direction, so as to drive the movable rod 400 to rotate in the horizontal direction. The second driving assembly 600 is installed on the support frame 100 or the rotating frame 200 and is connected with the movable rod 400. The second driving assembly 600 is used to drive the movable rod 400 to move in the vertical direction. Compared with the prior art, the driving module 10 provided by the application installs the lubrication stabilizer 300 on the support frame 100 or the rotating frame 200, and the lubrication stabilizer 300 is formed with the protrusion 320 in the through hole 310. After the movable rod 400 penetrates through the through hole 310 and abuts against the protrusion 320, the protrusion 320 restricts the movable rod 400 from shaking in the horizontal direction, so that the movable rod 400 is relatively stable during rotation or lifting. That is, the protrusion 320 can provide lubrication and guiding effects for the movable rod 400, so as to avoid abrasion between the movable rod 400 and the support frame 100 or the rotating frame 200. Moreover, the protrusion 320 can not only reduce the friction area between the movable rod 400 and the lubrication stabilizer 300, so as to further reduce the abrasion of the movable rod 400, but also can quickly dissipate the heat generated by the movable rod 400 during movement, so as to improve the service life of the driving module 40.

[0041] As shown in Figure 1 and Figure 6 The support frame 100 comprises a bottom plate 110, side plates 120, a top plate 130 and a mounting table 140. The side plates 120 are connected with the bottom plate 110 and the top plate 130 respectively, and the bottom plate 110 and the top plate 130 are oppositely and spacedly arranged.

[0042] Optionally, the top plate 130 is formed with a mounting hole 131, and a section of the mounting table 140 in the vertical direction is in an inverted convex shape. The mounting table 140 is installed on the top plate 130 by means of rivets or screws, and the mounting table 140 is partially accommodated in the mounting hole 131. It should be noted that in other embodiments, the mounting table 140 can also be clamped on the top plate 130. For example, the mounting table 140 is provided with a first clamping part, the top plate 130 is provided with a second clamping part matched with the first clamping part, one of the first clamping part and the second clamping part is a clamping column, and the other of the first clamping part and the second clamping part is a clamping groove.

[0043] Further, the mounting base 140 is formed with a mounting groove 141, and the mounting base 140 is formed with a through hole 142 at the groove bottom of the mounting groove 141. The mounting groove 141 and the through hole 142 are coaxially arranged and circular in horizontal cross section, and the cross-sectional area of the mounting groove 141 in the horizontal direction is greater than that of the through hole 142 in the horizontal direction.

[0044] It can be understood that, in the production process, the bottom plate 110, the side plate 120, the top plate 130 and the mounting base 140 can be integrally formed to omit the assembly steps of the bottom plate 110, the side plate 120, the top plate 130 and the mounting base 140, thereby improving the production efficiency.

[0045] It should be noted that, in other embodiments, the support frame 100 can also only include the bottom plate 110, the rotating frame 200 is rotatably mounted on the bottom plate 110, the lubricating stabilizing piece 300 is fixedly mounted on the rotating frame 200, the movable rod 400 is arranged through the through hole 310 and abuts against the lubricating stabilizing piece 300, and one end of the movable rod 400 is movably mounted on the rotating frame 200; the first driving assembly 500 is mounted on the bottom plate 110 and is in transmission connection with the rotating frame 200 to drive the rotating frame 200 to rotate in the horizontal direction; the second driving assembly 600 is mounted on the rotating frame 200 and is connected with the movable rod 400 to drive the movable rod 400 to move in the vertical direction.

[0046] Optionally, as shown in Figures 1 to 3 , the rotating frame 200 includes a rotating disc 210 and a sub-support 220, and the rotating disc 210 is rotatably mounted on the mounting base 140; one end of the sub-support 220 is fixedly mounted on the side of the rotating disc 210 away from the mounting base 140, and the other end of the sub-support 220 is suspended as a free end or rotatably mounted on the bottom plate 110, so that the rotating disc 210 can drive the sub-support 220 to rotate in the rotating process. It can be understood that, in the production process, the rotating disc 210 and the sub-support 220 can be integrally formed to omit the assembly steps of the rotating disc 210 and the sub-support 220, thereby improving the production efficiency.

[0047] Exemplarily, as shown in Figure 3 and Figure 7 , the rotating disc 210 includes a bottom wall 211, an inner ring wall 212 and an outer ring wall 213, the bottom wall 211 is formed with an avoiding hole 2111, and the cross-sectional area of the avoiding hole 2111 in the horizontal direction is greater than that of the through hole 310 in the horizontal direction, so that the movable rod 400 does not directly contact the rotating disc 210. The inner ring wall 212 is connected to the outer edge of the avoiding hole 2111, the outer ring wall 213 is connected to the outer edge of the bottom wall 211, and the outer ring wall 213 is spaced and arranged outside the inner ring wall 212.

[0048] Further, as shown in Figures 3 to 5 The rotating disc 210 further comprises a first induction piece 214 connected to the outer edge of the bottom wall 211, and the driving module 10 further comprises a first induction switch 180 mounted on the side plate 120 and matched with the first induction piece 214 for controlling the first driving assembly 500 to work. The first induction piece 214 is a sector-shaped induction sheet. When the first induction switch 180 senses the first induction piece 214, i.e. the first induction switch 180 is opposite to the first induction piece 214, the first induction switch 180 is in an open state, thereby controlling the first driving assembly 500 to start working. When the rotating disc 210 rotates to a certain angle, the first induction switch 180 cannot sense the first induction piece 214, i.e. the first induction switch 180 is misaligned with the first induction piece 214, and the first induction switch 180 is in a closed state, thereby controlling the first driving assembly 500 to stop working. It should be noted that in other embodiments, the first induction switch 180 can also be a sensor.

[0049] Optionally, as shown in Figures 1 to 3 The auxiliary support 220 comprises a bottom connecting plate 221, a side connecting plate 222 and a top connecting plate 223. The side connecting plate 222 is connected to the bottom connecting plate 221 and the top connecting plate 223 respectively, and the bottom connecting plate 221 and the top connecting plate 223 are oppositely and spacedly arranged. The bottom connecting plate 221 is rotatably mounted on the bottom plate 110, and the top connecting plate 223 is clamped on or mounted on the side of the bottom wall 211 away from the inner ring wall 212 by rivets or screws. It should be noted that in other embodiments, the auxiliary support 220 can also not comprise the bottom connecting plate 221, i.e. the end of the auxiliary support 220 away from the rotating disc 210 is a free end. In this way, the step of mounting the bottom connecting plate 221 on the bottom plate 110 can be omitted, the production efficiency is improved, and the parts required for installation are reduced, thereby reducing the production cost.

[0050] It can be understood that in the embodiment in which the support frame 100 only comprises the bottom plate 110, the rotating disc 210 is mounted on the bottom plate 110, the bottom connecting plate 221 is mounted on the side of the rotating disc 210 away from the bottom plate 110, the lubricating stabilizing piece 300 is mounted on the top connecting plate 223, and the second driving assembly 600 is mounted on the rotating disc 210 or the side connecting plate 222.

[0051] Optionally, as shown in Figure 2 and Figure 3As shown, the drive module 10 also includes a bearing 700, which is disposed within the mounting groove 141. The outer ring of the bearing 700 is connected to the mounting platform 140, for example, the outer ring of the bearing 700 is bonded to or snapped onto the mounting platform 140, or the outer ring of the bearing 700 is interference-fitted with the mounting groove 141. The inner ring of the bearing 700 is connected to the inner ring wall 212, for example, the inner ring of the bearing 700 is bonded to or snapped onto the inner ring wall 212, or the inner ring wall 212 is interference-fitted with the inner ring of the bearing 700. Compared to the direct rotatable connection between the mounting platform 140 and the rotating disk 210, the bearing 700, placed between the mounting platform 140 and the rotating disk 210, makes it easier for the rotating disk 210 to rotate relative to the mounting platform 140, thereby reducing wear and energy consumption. It should be noted that in other embodiments, the inner ring of the bearing 700 can also be connected to the outside of the mounting platform 140, while the outer ring of the bearing 700 is connected to the outer ring wall 213.

[0052] Optional, such as Figure 2 and Figure 3 As shown, the drive module 10 also includes a fastener 800. The lubrication stabilizing member 300 is mounted on the side of the inner ring wall 212 opposite to the bottom wall 211 via the fastener 800. The fastener 800 can be a rivet or a screw. It is understood that in other embodiments, the lubrication stabilizing member 300 can also be snapped onto the side of the inner ring wall 212 opposite to the bottom wall 211; or the lubrication stabilizing member 300 can also be mounted on the bottom wall 211; or the lubrication stabilizing member 300 can also be mounted on the top connecting plate 223.

[0053] Furthermore, such as Figure 3 and Figure 7 As shown, the inner ring wall 212 is provided with a limiting part 2121, which abuts against the bottom of the inner ring of the bearing 700. The lubrication stabilizing member 300 is installed on the side of the inner ring wall 212 away from the bottom wall 211 and then pressed against the top of the inner ring of the bearing 700. This allows the inner ring of the bearing 700 to be sandwiched between the limiting part 2121 and the lubrication stabilizing member 300, which can make the inner ring of the bearing 700 more stably connected to the inner ring wall 212.

[0054] Furthermore, such as Figure 3 and Figure 6As shown, the mounting table 140 is formed with a receiving groove 143 on the side wall of the mounting groove 141, the receiving groove 143 is annular, and the drive module 10 further comprises a crimping strip 900 arranged in the receiving groove 143 and pressed on the top of the outer ring of the bearing 700, so that the outer ring of the bearing 700 is clamped between the crimping strip 900 and the groove bottom of the mounting groove 141, and the outer ring of the bearing 700 is more stably connected to the mounting table 140. The crimping strip 900 is elastic and has a ring structure without connection between the head and the tail. When the crimping strip 900 is installed in the receiving groove 143, the diameter enclosed by the crimping strip 900 needs to be reduced and then put into the mounting groove 141, and then the crimping strip 900 is pressed to move to the receiving groove 143. When the crimping strip 900 is entirely arranged in the receiving groove 143, the crimping strip 900 will recover the elastic deformation.

[0055] It should be noted that in other embodiments, the lubrication stabilizing piece 300 can be clamped to the mounting table 140 or mounted to the mounting table 140 by the fastener 800. When the lubrication stabilizing piece 300 is mounted to the mounting table 140, the lubrication stabilizing piece 300 can be pressed on the top of the outer ring of the bearing 700, for example, the lubrication stabilizing piece 300 is formed with a flange arranged in the mounting groove 141 and extending to the top of the outer ring of the bearing 700. In addition, the drive module 10 further comprises a crimping piece clamped to the side of the inner ring wall 212 away from the bottom wall 211 or mounted to the side of the inner ring wall 212 away from the bottom wall 211 by a rivet or a screw, and the crimping piece is pressed on the inner ring of the bearing 700. In this way, the bearing 700 can be more stably connected to the mounting table 140 and the inner ring wall 212, respectively.

[0056] Optionally, as shown in Figure 3 and Figure 9 As shown, the lubrication stabilizing piece 300 is formed with a through hole 310 communicating with the avoiding hole 2111, and the lubrication stabilizing piece 300 is formed with a protrusion 320 in the through hole 310; the movable rod 400 is arranged in the through hole 310 and abuts against the protrusion 320. The protrusion 320 comprises a plurality of convex particles 321 arranged on the hole wall of the through hole 310 at intervals, and the contact surface between the convex particles 321 and the movable rod 400 is a spherical surface or a concave cylindrical surface matched with the movable rod 400, so that the convex particles 321 can not only reduce the friction area between the movable rod 400 and the lubrication stabilizing piece 300 and further reduce the wear of the movable rod 400, but also quickly dissipate the heat generated by the movable rod 400 during movement through the gaps between the convex particles 321, thereby improving the service life of the drive module 40.

[0057] Optionally, as shown in Figure 10As shown, the protrusion 320 includes multiple protruding rings 322, which are spaced apart along the extension direction of the through hole 310. The contact surface between the protruding ring 322 and the movable rod 400 is cylindrical, which reduces the friction area between the movable rod 400 and the lubrication stabilizer 300, further reducing the wear of the movable rod 400. Furthermore, the gaps between the protruding rings 322 allow for rapid dissipation of heat generated by the movable rod 400 during its movement, thereby improving the service life of the drive module 40.

[0058] Optional, such as Figure 11 As shown, the protrusion 320 includes a rib 323, which is spirally arranged. Alternatively, as... Figure 12 As shown, there are multiple protrusions 323, which are spaced apart in the circumferential direction of the through hole 310. The contact surface between the protrusions 323 and the movable rod 400 is a convex cylindrical surface or a concave cylindrical surface adapted to the movable rod 400. This allows the protrusions 323 to reduce the friction area between the movable rod 400 and the lubrication stabilizer 300, further reducing the wear of the movable rod 400. Furthermore, the gaps between the protrusions 323 can quickly dissipate the heat generated by the movable rod 400 during its movement, thereby improving the service life of the drive module 40.

[0059] Optional, such as Figures 1 to 3 As shown, the movable rod 400 includes a rod body 410 and a slider 420. The rod body 410 passes through the through hole 310 and the clearance hole 2111 and abuts against the lubrication and stabilizing member 300, so that the lubrication and stabilizing member 300 provides lubrication and guidance for the movement of the rod body 410. The slider 420 is fixedly installed at one end of the rod body 410 and slidably connected to both sides of the side connecting plate 222, so that the slider 420 can slide along the side connecting plate 222 in the vertical direction. Moreover, when the rotating disk 210 drives the sub-support 220 to rotate, the side connecting plate 222 can also drive the slider 420 and the rod body 410 to rotate.

[0060] Furthermore, such as Figure 1 As shown, the slider 420 includes a slider body 421 and a clamping part 422. The slider body 421 is slidably connected to the slide rail 224. The clamping part 422 is fixedly installed on the side of the slider body 421 facing away from the slide rail 224. The rod 410 is clamped between the slider body 421 and the clamping part 422, so that the slider 420 can drive the rod 410 to rotate when the follower side connecting plate 222 rotates. It can be understood that the end of the rod 410 near the slider 420 can be prism-shaped, so that the rod 410 can be clamped more stably between the slider body 421 and the clamping part 422.

[0061] Further, the auxiliary support 220 further comprises a sliding rail 224 extending in the vertical direction and mounted on the side connecting plate 222 and in sliding connection with the sliding block 420, so as to reduce the abrasion of the sliding block 420.

[0062] Further, the auxiliary support 220 further comprises a limiting piece 225 mounted on the side connecting plate 222 to limit the sliding of the sliding block 420 in the vertical direction, so as to limit the sliding of the sliding block 420 within a certain range, so as to improve the safety performance of the driving module 10. It should be noted that the limiting piece 225 can have multiple different position mounting positions in the length direction of the side connecting plate 222, so that the driving module 10 can set the limiting piece 225 according to the actual situation to adapt to test tubes of different heights. The placement table can thus expand the application range of the driving module 10.
